What if you get a setup that is designed for a larger engine, like say a 6 or 8?

You put on a header but then everything else is like 3" (or for a larger engine)you have all the stuff, cat, muffler, resonator but everything is so large it flows as good as a 2" race setup?

Or does it not work that way?

I would think with a setup larger then whats designed for the car emmisions wise would pass but be so much more un restrictive it would help the engine breathe better.
It's not important to win, it's important to make the other guy lose.
